Product Description

BK-887 is a modified bentonite for water-based systems

1. Advantages:
☆ High gelling efficiency in water-based systems.
☆ Excellent thixotropy property, sag resistance and viscosity control.
☆ Prevent hard settlement of pigment/fillers.
☆ Ease of incorporation and Ease of dispersion.
☆ Suite to wide PH range.

2. Typical Properties: 

Color	Appearance	Density	Moisture (@105ºC,2hrs)	Fineness through 200 mesh	PH value (10%suspension )
Light White	Free Flowing Powder	1.6g/cm^3	≤10.0%	≥95%	6-12

 
3. Typical Applications: 

Water-based paint&coatings	Cosmetics
Emulsion paint	Toothpaste
Adhesive	Grout
Sealant

4. Incorporations:
BK-887 can be added directly in powder form. No need for polar actiator or pre-gel. Recommended procedures are as follows:
 
  A. Water (PH:6.0-12.0, but most suitable between 7.0-8.0).
  B. BK-887 (Dispersing at high speed shear for 15-30minutes).
  C. Other additives (film-forming agent,dispersing agent,defoaming agent, etc.)
  D. Pigment and filler (Mixing and dispersing).
  E. Emulsion (Mixing).
  F. Post correct.

5. Recommended Levels:
The amount of BK-887 rheological additive required depends upon the specific system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-1.0% based on the total formulation weight.
